Quickbooks data migration from restored backup file

My company recently had a Quickbooks data file crash due to an immense amount of corrupted data. When they restored from backups, large sections of historical data were missing. After paying Quickbooks to do a rebuild of our database, they were able to restore pretty much everything up to about a month ago. As we still have the backups from right up to before the crash, I was able to create another restored database from the most recent backup made right before Quickbooks support began their rebuild, and can see the missing months data in the corrupted restored file, but the only way I can find to move it over seems to require the Accountant version of Quickbooks, and we have the version specific to our industry, which is the Manufacturing and Wholesale version. Is this the only way to get the data transfered?
